Ah, but you're assuming Pooh will somehow be incapacitated if his stuffing his ripped out. We just plain don't know how the rules work with him: maybe the cotton batten stuffing can continue to fight, and asphixiate Paddington, or the skin can keep on fighting and become a choking hazard. I just assume Pooh can regenerate and/or re-assemble, like the T1000 or Wolverine.
Winnie is basically a plush golem, so we have no way of knowing how powerful the magic is that drives him. But it's powerful enough magic that can give a piece of felt the ability to walk, talk and digest food, so I wouldn't mess with that noise, man.
Oh please, he's just another overpaid public service employee, who's only there just to cash out his pension. He's not going to fight for ****.
